Maintain Functions
The
Maintain In
and
Maintain Out
functions adjust the engine speed to keep the transducer level at the
Target Set
Point
. The
Servo Gain
adjusts how aggressively the throttle is adjusted while the
Servo Delay
controls how often the
throttle is adjusted.
Note:
When “
Maintain” is selected in either Dual SW or Single SW modes, the Transducer WILL NOT be
referenced for Start or Stop.
The direction of the throttle adjustment is dependent on the selected mode as shown in the table.

Dead Band
In some situations the transducer level may fluctuate around the
Target Set
Point
such as the water level on a windy day. To limit throttle hunting using
the maintain functions a dead band can be programmed. This value prevents
throttle adjustment while the level is within the band (see diagram). In
essence the speed is considered to be at the target whenever it is within the
dead band.
Note:
The dead band entered is amount above and below the target
point. For example, if the target is 5.0 feet with a 0.1 foot dead band,
the dead band is 4.9 to 5.1 feet.
CANplus Display
Soft buttons simplify the user interface by displaying a
button bar
above the buttons when any of the first 4 buttons
(buttons 1 to 4, starting from the left) are pressed. Icons on the button bar change to represent the current function
of each button. The button bar disappears after 5 seconds if no further buttons are pressed.
Note:
Different software versions may have slightly different displays.
Analog Gauge Pages
Analog Gauge Pages
provide four independent pages of analog gauges. To enable Analog Gauge Pages, press any
of the first 4 buttons to show the top level button bar and then press button 1
. Alternate pages are selected by
repeated pressing of button 1. The four standard gauge pages are shown below.

Page 2
Page 3
Page 4
Note:
Engine Hours are displayed as a digital value even on Analog Gauge Pages.
The default gauge pages represent 13 selections since the
tachometer is repeated in the upper left quadrant of each page.
All 16 gauges may be configured by the user to create an application-specific view
of CANbus data. Gauges on the current page can be changed via
Adjust Mode
,
accessed by pressing button 5
when the button bar is visible. Gauges can be
